IMPROVEMENT IN BLIND-SLAT STAPLES.

Specification forming part of Letters Patent No. 139.516, dated June 3, 1873 application led March 1'2, ll53.

To all whom it may concern:

Beit known that I, CHARLES H. PALMER,4

of the city, county, and State of N ew York,

have invented a new and useful Improvement in Staples for the Slats ot' Blinds; and I do hereby declare that the following is a full, clear, and exact description and specification ofthe same, reference being had to the accompanying drawing making part of this description, in which- Figure 1 is a side view of a blind-Slat with one ot' my sta-ples screwed in the center, ready to be drivelrdown to insert the short prong. Fig. 2 is a side view of slat with staple driven down ready for use. Fig. 3 is a side view of the staple.. Fig. 4 is an ledge view ofthe same.

.My invention relates to the eyes or staples used with the slats of a blind to unite the up- `right connecting-rod with the slat, and for combining all the slats together in the blind, for the purpose of opening and closing them; and to this end my invention consists in so constructing said staple that one prong may be inserted in the slat by screwing or driving, and the other prong, made much shorter and shaped to enter the wood by a blow, may prevent the staple from turning when thus bent and forced into the wood ot the slat.

In order that persons skilled in the art may A is the long prong ofthe staple, made of a suitable metal, and corrugated or screw-threaded to cause it to take arm hold ofthe wood of l the slat B. c is the eye or bend of the staple,

having a short prong, D, at olle side, shaped to enter the wood readily when struck by a blow. 1

The operation is as follows The staple being lirst driven or screwed into the blind-slant until the short prong of the eye nearly touches the wood, the staple is turned until the eye stands parallel, longitudinally, with the slat; then, by a blow, the eye is bent over, forcingthe short prong into the slat without materially moving the posit-ion ot' the long prong a.

l prefer the threaded prong, so that the staple may be screwed into the slat, but a roughcned one would answer.

Having now fully; described my invention, what I claim, and desire to secure by Letters Patent, is-

The blind-slet staple, substantially as' described.
